PROCESS'YOF STRIPPING AN CLEANING SUGAR-CANE.
SPECIFICATION forming part of Letters Patent No. 354,510, dated December 14, 18846.-
Application flled February G, 1886. Serial No. 101,107. (No model.)
To all whom, it may concern.-
Be it known that I, HENRY A. HUGHES, of
ltio Grande, Cape May county, New Jersey, have invented a new and useful Irocess ot' Stripping and Cleaning Sugar-'Cana of which the following is a speciiication.
, My invention relates more particularly to the treatment of sorghum-cane. I have discovered that the dark color and bitter taste of diffusion-juice obtained from sorghum-cane is due, chielly, to the steeping of the leaves and sheaths, a'nd, that it can be avoided by stripping the cane. The effect of the leaves .and sheaths in the diffusers is also to increase thc amount of water to be evaporated by thirtythree per cent., while the dark color of the juice resulting decreases the market value of the sirups by one-half.
In order to strip the cane effectually, I have devised a new process, which is the subject of my present application.
In the accompanying drawings I show certain instrumcntali ties which I prefer to employ for carrying my process into practical effect.
I do not limit myself to the particularinstrumentalities here represented,becanse I may use other means to accomplish the same purposes; neither do I herein claim the said instrumentalities, Afor the reason that they enter into the construction of a machine which will be made the subject ofaseparate application for Letters Patent hereafter' to be filed by me, in which application the said instrumentalities and the combinations involved in their construction and arrangementwill be fully described and claimed,of which notice tothe publicis hereby Only so much of the aforesaid instruunderstanding of a practical mode of carrying my aforesaid process into effect.` i
Figure 1 of the said drawings represents a s ide elevation and partial section of the assorting-aprons and stripping and brushing devices. Fig. 2 shows the arrangement of separating slats and partitions on one of the assort-ingaprons. Fig. 3 is a longitudinal section'of so much of one of the stripping devices as is necessary to show the mode. of treatment of the cane by the stripping pins and brushes.
Similarl letters of reference indicate' like parts. 5Iiirst cut the cane, by any suitable means,
into short lengths of about four inches. j The pieces so cut are conveyed into an elevated receptacle, whence they pass to theinclined chute A. At the lower end of this chute is a gate, a, which is intermittentlyopened to allow of the outward delivery of the pieces.
Beneath the chute Ais a sizing or assorting endless apron, B, which passes o'ver revolving rollers C C', whereby the upper surface of the apron is caused to travel in the direction of the arrow 1. Upon the apron are attached spacing-slats D, and between these slats `are secured vert-ical partitions E. The slats and partitions are fastened to the apron at their lower sides only, so that they easily pass around the rollers C C'. The partitions E extend transversely across the apron, but are not present over its entire area, being omitted between the spacing-slats at the part F of saidi apron, which at such part has a. substantially smooth surface.
As is well known, the cane-stalk varies in thickness, and hence the. pieces which fall upon the apron B from the chute are? of various'diameters. The object of the apron B is to separate from the mixed pieces all those exceeding, say, one and one-half inch in diameter. To thisend the spacing-slats D are made of lsuch width as to render the intervals between t-he partitions E equal to one and onehalf inch hence such pieces of the cane as are less than one and one-half inch in diameter will fall between the said partitions E, but all pieces of larger diameter will rest upon the. upper sides of said partitions.
Above the apron B is disposed a rotating brush-wheel or pair of brush-wheels, G. This wheell or wheels is revolved in such direction as that when the large pieces resting on the partitions E are -by the forward movement of between which the pieces of cane arereceived. The 'object of the apron H is to carry A the cane rearward and to cause it tofall upon an inclined plane, K, by which it is delivered',
upon an endless traveling apron, B', similar in all respects to the apron B, except that the transverse partitions E thereon are separated by smaller intervals than the partitions E on the apron B-say for a distance of one and three-eighths inch. The consequence then is, that all pieces of a less diameter than one and three -eighths inch will enter the spaces between the partitions E', while all pieces of larger diameter will be brushed back by the rotating brush-wheel G upon the tops of the partitions E', as before. The small pieces between the partitions E are now carried over the roller and caused to fall upon an endless traveling apron, H', in all respects similar to the apron H, and thence fall upon another apron, B, similar to t-he aprons B B', except that the partitions thereon are still more narrowly spaced. There may be any number of aprons, as B' i X X B2 B, thus successively arranged, each apron causing the separation of all the pieces exceeding a certain limit in diameter, until finally only small pieces of minimum diameter fall upon the last and lowest apron, B3. Returning 110W to apron B, the large piecesY thrown back by the brushes G remain upon the tops of the partitions E until the smooth portion Fof said apron reaches the brushes, when the pieces fall upon said portion. Meanwhile said smooth portion has traveled beneath the mouth of the .chute A, and during the time of its movement the gate a is closed, so that no pieces of cane are delivered thereon. When thesaid part F comes over the apron-roller C', then aslide, L, (which hitherto has been kept raised, and hence away from the apron B,) falls, so that the pieces can pass from the apron upon this slide.
Referring next to Fig. 3 and the devices shown at the 1right-hand side of Fig. 1, at M are slats supported at their ends by endless chains or bands O, which pass over rollers N.
There are consequently open spaces between said slats, and the slat apron so formed moves slowly in the same direction as the apron B. The depth of the slats (vertical height) in the several slat aprons shown depends upon the diameter of the assorted pieces of cane deliveredV to each slat apron. The depth of the slats in each slat apron should be slightlyless than the diameter of the pieces of cane supplied to it.
Disposed respectively above and below each slat apron are broad plates or 4planes P and Q. To one of these plates is connected a mechanism for causing it to reciprocate in a longitudinal direction--as, for example, the crank and pitman B. By any suitable mcans` as, for example, racks and pinion, indicated by dott-ed lines, as in Fig. 3-the'movement of one plate is transmitted to the other, so that while one plate travels forward the other moves backward, and vice versa.
On the under side of the upper plate are attached sharp points or pins S. Similar pins are secured to the upper side of the lower plate at T. On the under side of the upper plate in rear of the pins are brushes and similar opposing brushes, V, are fastened to the up per side of the lower plate.
In order to prevent the cane from dropping through the open spaces bet\veeirtlie slats M when the lower plate, Q., is rcciprocated, thin plates NV are secured at each end of said plate Q, which plates NV slide over the fixed barsv X. As the plates I and Q are rapidly reciprocated back and forth the sharp pins S and T- rnb over and under the pieces of cane which rest between the slats M, and as'the depth of these slats is slightly less than the diameter of the cane, it followsthat the pins can enter fol' a short distanceiuto the sheath upon the cane and so tear oil'A the same. The cane'is meanwhile being slowly carried forward by the movement of the slats; but as this motion is much slower than that of the plates l and Q, the pieces are forcibly brought against the sides of the slats, which thus Support and hold them in opposition to the rnbbi n g action. As the cam.` passes from between the pins S and T it cncounters the brushes U and V which complete the removal of the sheath, or ol' any adhering fragments, and polish the surface. Finally, the pieces fall off the ends of the slat aprons into a chute which communicates with a blower, Y, or other means of creating an airblast, which drives oft' the dust and fragments.
The stri pping and brushing devices arranged iu rear of each apron B X X are alike, except that in each successive slat apron the depth of the slats corresponds to the decreasing intervals between the partitions E E', &e., this of course being necessary, because the diamer- Y'ter of the separated pieces of cane constantly diminishes, and hence the stripping pins and brushes must be placed gradually nearer together in order effectually to operate upon the surfaces of the pieces.
vReferring now to the last asserting-apron,
B3, itwiu be observed that uns differs from the preceding apronsB B X X B2 in having no smooth portion, like the part F of apron B. This is not necessary, inasmuch as all the pieces upon the apron are thrown off upon the inelined chute Z, which remains always down, and from which the pieces pass to the last scratching and brushing apparatus, whence they are delivered into the exit-chute with those from the scratching and brushing devices above. Means (not necessary to show here) are provided whereby the delivery of pieces of cane from the apron H to the apron B is checked during the passage of the smooth.
port-ion of the apron B beneath the plane K, and I also arrange other mechanism for driving the aprons and operating the slides L and the blower Y, which is not herein shown or described.
Having now set forth a practical means of carrying my process into effect, I proceed to define my said process, which has for its object the separating and stripping ofthe sections of cane in order to remove leaves and sheaths therefrom preparatory to diffusing; and
the surfaces.
the said process consists, first, in dividing the cane into suitable lengths, then separating from the bulk or mass of pieces al1 those above or below a certain diameter,then scratehin g or abrading, as by sharp pins, the pieces so separated, in order to detach and remove, so far as possible, the adhering leaves and sheaths, and then brushing the pieces so treated to remove' any -remaining adherentV portions and polish I may carry out this process as already described by separating the pieces into two or more sizes of different diameters, and then delivering the pieces of each size, respect'- ively,into scratching and brushing apparatus. I may effect the separation into the several sizes, as herein set forth, successively, and scratch and brush the separated pieces, the pieces of each size, in an apparatus adapted` thereto, the series of apparatus operating simultaneously,
1. The process of stripping sugarcane, which consists, first, in dividingsaid cane into short lengths; second, assorting thesaid lengths to separate therefrom all pieces of a diameter exceeding a certain limit; third, subjecting said last-mentioned pieces to scratching or abrasion, wherebyv the leaves and sheaths thereon are loosened or removed, and, fourth, subjecting saidlast-mentioned pieces to brushing, whereby any remaining adherent matter is removed and the surface of the cane smoothed `-and polished, substantially as described. l l
2. The process of stripping sugar cane, which consists, first, in dividing said cane into short lengths; second, assorting thesaid lengths with reference to theirdiameters into two or more sizes; third,subjecting`the pieces of each size to scratching or abrasion in devices respectively adapted to each size, whereby the leaves and sheaths thereon are loosened or removed, and, fourth, subjecting the pieces of each size to brushing in devices respectively adapted to each size, whereby any remaining adherent matter is removed and the surface of the cane smoothed and polished, substantially as described.
3. The process -of stripping sugar cane, which consists, first, in dividing said canento short lengths; second, assorting said lengths with reference to their diameters into two or more sizes, the said sizes being assorted successively; third,simultaneously subjecting the pieces of each size tovscratching or abrasion in devices respectively adapted to each size,.
whereby the leaves and sheaths are loosened or removed,and, fourth, simultaneously subjecting the pieces of each size'to brushing yin devices respectively adapted to each size, whereby any-'remaining adherent matter is removed andthe surface of the cane smoothed and polished, substantially as described.;
